Trading standards officers are working with Spanish police to end a lottery scam after a Staffordshire man was conned out of money.
They say the man from Stafford could have lost £7,500 after receiving a letter telling him he had won the Spanish lottery, El Gordo.
The man was told he had won £750,000 but had to buy a bond to cover insurance for the money.
Several people have already been arrested in Spain.
Trading Standards officials say the victim was advised to pay £1,000 for every £100,000 of winnings.
But investigations later proved the company mentioned in the letter did not exist, the address of the lottery company was wrong and the phone number was in America.
They now plan to pass details of the attempt to introduce it to Britain to Spanish police.
